STOVE.

Specification of Letters Patent.

Patented May 25, 1920.

Application filed December 30, 1918. Serial No. 268,814.

To all 'zc/0m t may concern:

Be it known that I, CLEVELAND Gr. TERRY, a citizen of the United States, residing at Los Angeles, county of Los Angeles, and State of California, have invented a certain new and useful Improvement in Stoves, of which the following is a specification.

My invention relates to a heating device and has especial reference to stoves of the type generally known as air tight stoves, an object of the invention being to provide a simple, economical and efficient stove, which will produce a continuous circulation of air in a room and thus prevent the accumulation of noxious gases and odors.

Other objects of the invention are to provide a stove which will at all times evenly distribute the heat, and in which the heat may always be under perfect control, and the life of the stove be materially prolonged by avoidance of spasmodic temperatures which, in stoves of present construction7 causes their quick deterioration and ruin.

Other objects will appear from the subjoined specification, in connection with the accompanying drawing, which represents a preferred form of embodiment of the invention, and in which- Figure 1 is a vertical sectional view.

Fig. 2 is a horizontal section on line 2 2, Fig. 1, and

Fig. 3 is a plan view of the inclosure, showing the air control therein.

The stove consists of a body 1, having a top 2, stove pipe 3, and bottom 4, upon which is built the lire. The bottom 4 is provided with two oppositely disposed openings 5 and 6, communicating with passageways or air vents 7 and 8, formed preferably by semicircular plates 9 and 10, respectively riveted or otherwise fastened to the bottom and Walls of the body 1 of the stove. Over the top of the passageway 7, is preferably placed a deflector 11, for directing the air downwardly upon the ire, and the plate 10, forming the passageway 8, is, by preference disposed under the stove pipe 3, for obvious reasons.

Onto the underside of the bottom 4 is fastened an inclosure 12, the top of which is covered by the bottom 4, and the bottom of which inclosure 12 is provided with an aperture 13, and concentric gr'ooveways 14 and 14. @ne wall of the inclosure is provided with slots 15 and 15, through which extend the branches 16 and 16 of a damper or air control 17, which branches are seated, and are operable in said grooveways 14 and 14', by a handle 18, to control the passage of air entering through said aperture in the bottom of said inclosure to either the passageway 7 or 8 or both, as desired.

ll/hen the damper is lin central position or that shown in Fig. 3, both branches thereof extend approximately half way across the inclosure in which they are contained, permitting thereby the circulation of air through both passageways 7 and 8, and maintaining the fire in the stove at an even temperature and insuring a uniform circulation of air and heat radiated from the stove in a room, when the fire is well started. y

When starting the fire, however, the damper 17, is moved preferably to close entirely or partially communication between the opening 13 and the passageway 8, such operation establishing communication ibetween the opening 13 and they passageway 7. After the lire is started sufficiently, the damper 1T may be moved to central position, as shown in Fig. 3, or may be moved to close entirely communication between the aperture 13 and the passageway 7 and establish communication between aperture 13 and passageway S, thereby closing olf the air from the lire except sufficiently for a steady, uniform and ideal glow, particularly where coal is the fuel, and at the' same time creating a healthful circulation of heated air through a chamber. The cold air then enters through the aperture 13 and passes upwardly through the passageway 8, and then into the stove pipe with the radiated heat from the stove. The stove pipe being thus kept cool, prevents the creation of a vacuum, which would cause a high draft and produce an intense combustion of the fuel, with ensuing detriment to the stove. Hence by means of this damper, an even combustion of fuel, a perfect radiation of heat and a steady circulation of air may be had, with a resultant economy in fuel.

llhat I claim is 1. A stove comprising a closed body having a stove pipe and a bottom provided with oppositely disposed inlets, said body provided with oppositely disposed air vents in communication with said inlets and extending to near the top of and having free communication with the interior of the stove body, one of said vents disposed approximately in line with but spaced from said stove pipe, and means to regulate the supply of air to both said air vents or positively to prevent the passage of air to one of said vents While permitting it to the other.

` 2. A stove comprising a closed body having a stove pipe and a bottom provided With oppositely disposed inlets, means Within said body forming: vertical passagevvays communicating With the inlets in said bottom, both of said passageways extendingy to near the top of and ini freey Communication Withfthe interior of said body one of said passageways disposed. approximately in line Withfsalid stove pipe, a defleetor above the ing a stove pipe and a bottom provided With oppositely disposed air ports, said body provided with oppositely disposed air vents in communication with said ports and extendL 'ing to near the top of and having free communication With the interior of said body, and one of said vents disposed approximately in line-With said stove pipe, an inolosure fastened to the underside of the bottom of said kbody and communicating with the ports therein, and' with said vents, said inelos-ure having a central airaperture, andl a vertical air' control in said inelosu-rehaving tWo branches extending normally tok approximately the center of said inelosureand operablev about said eentral aperture to regulate the supplyoi air to bothsaid air4 vents or positively to prevent the passage of air'to one of saidl vents While permitting it to the other.

InV testimony whereof Ihaveset my hand in the presence of'two Witnesses.
